Adam's apple The Adam's apple, in conjunction with the thyroid cartilage which forms it, helps to protect the walls and the frontal part of the larynx, including the vocal cords (which are located directly behind it).n women, the bump is much less visible and is hardly perceived on the upper edge of the thyroid cartilage. The meeting point of the two portions of the cartilage generally forms an acute angle (of about 90°) in men, while in women it forms an open arc (of about 120°).

Gross Anatomy The larynx is composed of 3 large, unpaired cartilages (cricoid, thyroid, epiglottis); 3 pairs of smaller cartilages (arytenoids, corniculate, cuneiform); and a number of intrinsic muscles (see the image and video below). The hyoid bone, while technically not part of the larynx, provides muscular attachments from above that aid in laryngeal motion. [1, 2, 3, 4, 5] Larynx anatomy.

- The Epiglottis is known as the lid for the larynx. It is made up of ELASTIC cartilage. When you swallow, your epiglottis closes off your larynx leaving the only open passage … the esophagus. This is why we cannot breathe and swallow at the same time. Look up swallowing on You Tube and you'll find lots of good videos that will give you a visual of this mechanism.

Trachea (Windpipe) Four layers of tissues make up the walls of the trachea: 1  The mucosa is the innermost layer and consists of ciliated pseudostratified columnar epithelium with many goblet cells. 2  Deep to the mucosa is the submucosa layer, which is made of areolar connective tissue containing blood vessels and nervous tissue.

Chapter 53: The pharynx and larynx The larynx is the organ that connects the lower part of the pharynx with the trachea. It serves (1) as a valve to guard the air passages, especially during swallowing, (2) for the maintenance of a patent airway, and (3) for vocalization. The anterior aspect of the larynx is quite superficial (fig. 53-8) and the posterior aspect of the larynx is related to the laryngopharynx, the prevertebral fascia and muscles, and to the bodies of cervical vertebrae 3 to 6.

The larynx is a tough, flexible segment of the respiratory tract connecting the pharynx to the trachea in the neck. It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway.

The Pharynx, Larynx, and Trachea The framework of the larynx is made up of cartilage held together by membranes and ligaments: 1  Thyroid cartilage: The thyroid cartilage is the largest structure in the larynx. It is made up of two pieces of hyaline cartilage that meet in the front and middle to form the laryngeal prominence, or Adam’s apple. The posterior portion of the cartilage forms two horns, the superior horn and the inferior horn.

1b. The Trachea and Bronchi The cartilages are placed horizontally above each other, separated by narrow intervals. They measure about 4 mm in depth and 1 mm in thickness. Their outer surfaces are flattened in a vertical direction, but the internal are convex, the cartilages being thicker in the middle than at the margins.

What are the cartilage pieces that make up the larynx? The thyrohyoid membrane is a ligament associated with the thyroid cartilage that connects the thyroid cartilage with the hyoid bone. Cricoid Cartilage: A ring of hyaline cartilage that forms the inferior wall of the larynx. It is attached to the top of trachea.he paired cartilages of the larynx are the arytenoids, corniculate, and the cuneiforms. Thyroid Cartilage: This forms the Adam's apple. It is usually larger in males than in females.

The Respiratory System Air passes through the open larynx and through the trachea, which is 10-12 mm in diameter and held in shape by U-shaped cartilage rings. There are perhaps 23 levels of bifurcation leading to the left and right lungs. Bronchi are the left and right initial bifurcations, and sequential bifurcations, containing cartilage.
